So I’m thinking they have villages that are underwater. The villagers that live there could be a new type of villager called the Aquatic Villager and they would be green or blue and have gills and sea monster ears. There would also be Aquatic Golems to protect them from Drowns and another new mob I thought of called Aquatic Pillagers. Aquatic Pillagers would be unhinged Aquatic Villager looking sea monsters that are chalk white colored like normal and their leader would have a waterproof banner. It would be waterproof from their magic. The other new mob that there would be would be the Aquatic Ravager which instead of fur would have gills and sea monster ears and be yellow. The final new mob would be the Aquatic Witch who would like a normal Aquatic Villager just with a witch hat on of course they would be light green. What do you think?
